Endangered songbirds are losing their chance to learn mating calls, putting species at risk

Scientists worry that the world is losing about 1% or 2% of its insects each year.
WASHINGTON (AP) - Male songbirds usually learn their tunes from adult mentors. But when aspiring crooners lack proper role models, they hit all the wrong notes — and have less success attracting mates.
For five years, ecologist Ross Crates has tracked the singing ability and breeding success of critically endangered regent honeyeaters. These distinctive black and yellow birds were once common across Australia, but habitat loss since the 1950s has shrunk their population to only about 300 or 400 wild birds today.
